Enceladus’ tiger stripes are known to be spewing ice from the moon’s icy interior into space, creating a cloud of fine ice particles over the moon’s south pole and creating Saturn’s mysterious E-ring. Evidence for this has come from NASA’s Cassini spacecraft that orbited Saturn from 2004 to 2017. Pictured here, a high resolution image of Enceladus is shown from a close flyby. Tiger stripes are visible in false-color blue. Image credit: NASA / ESA / JPL / SSI / Cassini Imaging Team.

Astronaut David R. Scott, commander, gives a military salute while standing beside the deployed United States flag during the Apollo 15 lunar surface extravehicular activity (EVA) at the Hadley-Apennine landing site. The flag was deployed toward the end of EVA-2. The Lunar Module, ‘Falcon,’ is partially visible on the right. Hadley Delta in the background rises approximately 4,000 m (about 13,124 feet) above the plain. The base of the mountain is approximately 5 km (about three statue miles) away. This photograph was taken by astronaut James B. Irwin, lunar module pilot. While astronauts Scott and Irwin descended in the Lunar Module to explore the Moon, astronaut Alfred M. Worden, command module pilot, remained in lunar orbit in the Command and Service Modules. Image credit: NASA / JSC.
